BICYCLE-LOCK.

.SPECIFICATION forming part of Letters Patent No. 562,880, dated J' une 30, 1896.

Application led April 29, 1895. Serial No. 547,562. (No model.)

To a/ZZ whom it may concern,.-

Beit known that we, EDWIN CARL BAILEY and WILLIAM SAMUEL POND, citizens of the United States, residing at Janesville, in the county of Rock and State of Vfisconsin, have invented certain new and useful Improvements in Velocipede-Locks; and we do declare the following to be a full, clear, and exact description of the invention, such as will en able others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

Our invention relates to velocipede-locks, and has for its object the construction of a simple combination sprocket-wheel lock that may bedet-achably fixed upon the frame of a machine; that may be easily and rapidly operated 5 that can be manufactured and sold at the lowest price, and that will in all respects and fully perform the duties of the padlock, key, and chain now very generally used, and obviate the necessity for the rider to carry any part of the locking apparatus.

O ur invention consists, essentially, of a suitable casing and connections for fixing the same upon the frame of a velocipede, a bolt so arranged that it may be projected from and withdrawn into the casing when certain slotted disks, also inclosed by the casing, are moved into predetermined positions by a graduated, revoluble dial-head, as hereinafter described in detail.

In the accompanying drawings, wherein thc same letters designate the same parts th roughout, Figure l represents a vertical longitudinal sectional view of the lock, showing the portion of the frame lupon which it is placed, the position of the sprocket-wheel, and the bolt in engagement with the wheel. Fig. 2 represents a perspective view of the rightliand slotted disk shown in the irst gure; Fig 3, a side view, and Fig. fi a perspective of the left-hand disk. Fig. 5 represents a side view of the graduated revoluble head. Fig. 6 represents a side view of the bolt, showin g the lugs thereupon. Figs. 7 and 8 represent the exterior of the upper half of the casing and the interior of the lower half, showing the pierced ears through which rivets or screws pass to hold the halves together. Fig. 9 represents a cross-section view, upon the line X X of Fig. l, showing lock, rod of the frame, and the band binding them in contact. Fig. l0 represents a side view of the lock, band, and portion of the frame.

Referring to Fig. l, a represents a sprocketwheel; Z2, a portion of the frame; c, the band (see Figs. 9 and l0) surrounding lock and frame; CZ, the bolt, (see Fig. 6;) e e, the upper and lower halves of the casing, interiorly identical, and each provided with ears f f, all alike, and so situated as to exactly meet in couples when the halves of the casing are properly combined. As the halves e e have corresponding interiors, a description of one will answer for both.

In Fig. 8, Z marksa rectangular depression forming one-half of the slideway for the bolthead d. The shape of the slideway, it will be noticed, prevents the bolt from rotating. 0 o o represent interior ribs between which the slotted disks i and j lit closely. Ve may conclude to construct the disks less in thickness than shown in the drawings and to introduce washers of suitable material in order that the friction-resistir] g rotation of the disks may be set at any desired amount. Returning to the casing, an inspection of Fig. Swill show that the remaining ends of the two halves are partly closed, leaving, when combined, a central aperture, to be further mentioned. g represents the small bolts clamping the ends of the band together. (See Figs. l and 9.) 7L represents the graduated dial-piece provided with a central oritice movably iitting the stem of the bolt, and having an annular recess, within which the partly-closed en ds of the halves e fit movably. (Sec Fig. l.) This construction, when the casing is integrated about the dial-piece, allows the latter a rotative but not a longitudinal movement, and maintains its relative position. The form of the dial-piece is best shown in Fig. 5, wherein the projecting pin 7c is also represented at= tached to the inner face of the piece. m marks the cylindrical stem of the bolt CZ, and n n the lugs upon the stem. (See Fig. 6, wherein a button is shown as terminating the part As ordinarily constructed the stem is provided with threads near one end, intended to IOO "and contiguous groove, but having perpendicular pins s s projecting from both sides. The disks are disposed as shown in Fig. 1,j upon the right-hand side, i upon the left and nearer the dial-piece.

The various elements of our invention may be assembled and its operation described as follows: The stem m is passed through the central orifice of the dial-piece h, through the central orifices and grooves oft-he disks,l

then inserted into the bolt CZ. The parts so combined are now laid in one of the halves e, the bolt CZ occupying the depression Z, the disks being placed in proper order between the ribs o o o, and the annular recess of the dialpiece arranged to engage the partlyclosed end of the half-casing, as already eX- plained. It will be seen that the grooves in the disks may now be each dierently alined with respect to the lugs upon the stem of the bolt, the degree-marks upon the dial-piece, and a point set upon the casing or either of the two lines indicating the junction of the halves. A turn of the stem to right or left changes the location of the lugs and leads to a new combination. `When the relative positions of the parts are chosen, the stem is securelj7 fastened to bolt (l and the other half of the casing fixed in place. The lock may now be bound to a selected portion of the frame in proximity to the sprocket-wheel, (see Figs. l and 9,) the exterior groove of the casing (see Fig. 7) aiding the operation, as shown. As usually constructed and arranged, a movement of the dial-piece in one direction alines the disk i, and when the bolt has been partly retracted and one lug n has passed through the groove unti l just free of the disk i the dial-piece mustfbe turned in the opposite direction to place the groove p in disk j, opposite the adjacent lug, whereupon the withdrawal of the bolt may be completed. The arrangement outlinedV adds to the effectiveness of the combination, although a combination could be arranged permitting the dial-piece to be turned in one direction only. A reversal of the movements set out immediately above enables the bolt to be again advanced between the teeth of the sprocketwheel. After a short acquaintance with any given combination the operator can lock and release his machine with considerable rapidity.

Ne are aware that locks have been'contrived to rendervelocipedes inoperative by limiting the rotation of the sprocket-wheel, and we do not claim that feature broadly.

Having thus fully described our invention. what we do claim, and desireto protect by Letters Patent, is

In a lock for velocipedes, the combination of a divided casing yconsistingof interiorlyidentical parts, means for attaching said parts to the frame of a velocipede and to each other, a non-revoluble bolt having a cylindrical, detachable stem provided with lugs, the said stem passing centrally through the casin g, disks having central oriiices permitting the passage of the stem, said disks having grooves adjoining said orifices adapted to permit the passage of the lugs, the said disks being provided with projecting pins and arranged to be rotated within said casing but held against lateral motion, a graduated dial-piece surrounding` the said stem and revolubly attached to the casing, said dial-piece provided with a projecting pin, substantially as ser forth.
